▶ Roguelike deckbuilder ‘Slay the Spire 2’ hits early access
▶ Steam Global Sales #1, Overwhelming Positive Reviews…Continuing to Break Genre Records
The official sequel to the indie game ‘Slay the Spire’, which is evaluated as having virtually created the roguelike deckbuilder genre , ‘Slay the Spire 2’ was released as PC (Steam) Early Access on March 5th.
This game, developed by Mega Crit over five years, crashed Steam’s payment servers immediately after its release, recording a peak concurrent player count of 217,932 . This is an all-time record in the roguelike deckbuilder genre, and is approximately four times the previous game’s lifetime peak concurrent player count of 57,025. Even on the morning of March 6th, the day after its release, the number of real-time players maintained around 200,000, continuing its steady upward trend.
The indie game that took down Steam servers
On the day of release Slay the Spire 2’s impact far exceeded expectations. Shortly after its Early Access release, the Steam store page temporarily crashed, and errors occurred during purchases. The server outage, which lasted approximately 30 minutes, was attributed to the explosive influx of users.
Same day Slay the Spire 2 dominated the Steam charts with a peak concurrent player count of 217,932 . This figure more than doubled the concurrent player count of Bungie’s new AAA FPS, Marathon, which was released on the same day, which was around 86,000.
Slay the Spire 2 rose to the top spot on Steam’s global sales chart upon its release. While the previous title, Marathon, was available for pre-order, Slay the Spire 2 is gaining even more attention because it was only available for purchase after its release. User reviews are also overwhelmingly positive. As of the day after its release, over 2,000 reviews have received “overwhelmingly positive” ratings.
Prequel Slay the Spire initially launched in Early Access in 2017, but the IP itself was largely unknown, resulting in very low concurrent player counts. However, word-of-mouth spread quickly, selling over 1.5 million copies immediately after its 1.0 release. The sequel, true to its name, has been met with explosive reactions from the start, setting new records.
“A Sequel Decided on a Coin Toss”… Megacrit’s 5 Years
The story behind the creation of Slay the Spire 2 is a famous “coin flip.” During the COVID-19 pandemic, Megacrit was considering its next project. Co-founders Anthony Giovannetti and Casey Yano decided to flip a coin between a new game prototype Yano had in development and a Slay the Spire sequel Giovannetti had been working on. The sequel won.
Development was not smooth. While the initial two years were spent developing on the Unity engine, MegaCrit issued a strong public statement criticizing Unity’s 2023 announcement of a change to its install-based runtime licensing policy. Despite subsequent setbacks, including Unity’s retraction and the resignation of its CEO, MegaCrit fully transitioned to the open-source Godot engine .
After a massive undertaking of moving about two years’ worth of development to a new engine, the current Slay the Spire 2 was completed.
Completely rebuilt with the Godot engine, but the core loop remains the same.
Slay the Spire 2 is not just a simple content expansion, it is a complete rebuild from the ground up on the Godot Engine.
The core technical changes include a modular framework designed for flexible animation and multiplayer support via Spine2D. While the core loop—deck building, relic collection, and risk-reward judgment on branching maps—remains the same as in the previous game, peripheral elements such as build diversity, class identity, and map composition have been significantly expanded.
Full native Linux support is provided without middleware plugins, and Steam Deck is also fully supported from day one.
New characters, new co-op… Key Early Access content
The Early Access version launched with significantly more content than its predecessor. Five playable characters return, including Ironclad, Silent, and Defect, while two new characters specializing in vitality manipulation and summoning, Necrobinder and Regent, join the roster. One previously unreleased character, revealed in the trailer, will also be added at a later date.
For the first time in the series , a four-player online co-op mode has been introduced. Players can perform their actions simultaneously, minimizing waiting times. Team-specific cards and a combo system have also been added, enabling cooperative strategic play where one player’s debuff enhances the attack effectiveness of their teammates.
Inspiration from ‘Hades’ and ‘Elden Ring’
Megacrit is The development team directly cited Hades and Elden Ring Nightreign as influences on the development of Slay the Spire 2. While the original game created the genre, the development team’s position is that the sequel aimed to take it to a higher level by referencing various roguelike games that emerged afterward.
Megacrit also emphasized that community feedback, fan creations, and strategic research played a crucial role in the long-term success of the original game. This sequel also plans to evolve the game alongside players.
Users: “Even though it’s in early access, it’s already complete and better than its predecessor.”
Slay the Spire 2 maintains an “Overwhelmingly Positive” rating on Steam, with 97% of 2,145 reviews positive . Users are citing improved art and animation, new systems, and expanded content, saying the game “feels more polished than its predecessor, even in Early Access.”
Even in communities like ResetEra, there are continuous reviews saying, “It has become smoother and more beautiful while maintaining the feel of the previous work,” and among Steam Deck users, there are even jokes saying, “I bought Steam Deck because of this game.”
While some have pointed out similarities to the previous game, the counterargument that “it’s a sufficiently fresh experience, with so many new characters, cards, and systems added” is gaining more traction. Furthermore, confidence in MegaCrit’s community-driven early access development approach, demonstrated in the previous game, remains high.
Just as Slay the Spire practically birthed the roguelike deckbuilder genre, Slay the Spire 2 has been making indie game history since its release. Not only did it dominate the Steam charts with over 200,000 concurrent users, but it’s also been receiving rave reviews from both the community and critics, praising its “high level of completion despite being in Early Access.”
After a five-year development process and engine migration from Unity to Godot, this sequel marks the beginning of a long journey. MegaCrit plans to continue developing the game further, adding cards, characters, events, and other content based on community feedback.
If the original game created a genre, the sequel is once again climbing the Spire towards its pinnacle. With Slay the Spire 2 now in Early Access, gamers around the world are once again focused on the Spire’s peak, eager to see how it will be completed.
